Samenvatting

Natural populations are persistently exposed to environmental pollution, which
may adversely impact animal physiology and behaviour and even compromise
survival. Responding appropriately to any stressor ultimately might tip the scales
for survival, as mistimed behaviour and inadequate physiological responses may
be detrimental. Yet effects of legacy contamination on immediate physiological
and behavioural stress coping abilities during acute stress are virtually unknown.
Here, we assessed these effects in barnacle goslings (Branta leucopsis) at a historical coal mine site in theArctic. For three weeks we led human-imprinted goslings, collected from nests in unpolluted areas, to feed in an abandoned coal mining area,where they were exposed to trace metals. As control we led their siblings to feed on clean grounds. After submitting both groups to three well-established stress tests (group isolation, individual isolation, on-back restraint), control goslings behaved calmer and excreted lower levels of corticosterone metabolites. Thus, legacy contamination may decisively change stress physiology and behaviour in long-lived vertebrates exposed at a young age.
